My iPhone 5S is dying. The power button is on it’s way out and batteries are running out faster than ever, so I was looking for a power bank that I could put in with my camera bag when I’m out and about, or leave in the glovebox of my car. I ended up with this mini bluetooth keyboard with 5000mAh power bank. It’s got a keyboard built into it which is great as I hate typing on the iPhone, especially on WhatsApp!
I bought it from MobileZap.
